In communications and information processing, code is a system of rules to convert information-such as a letter, word, sound, image, or gesture-into another form or representation, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium.
A code is a set of symbolic strings ("code groups") that are listed, along with their assigned meanings, in a code book.
Codes encrypt messages by substitution, that is, they substitute code groups for components of the original message. "Kill the king at midnight" could thus be encoded, for example, as "OAKEN 7890 SPINDRIFT." Without the code book, it would be difficult for a reader of the encoded message to form an idea of its meaning.
Either a word or a number can be used as a code group.de groups that are words are termed code words and those that are numbers are termed code numbers. Note that a single code group can encode a single word ("king") or an entire phrase ("deliver the films to agent number 3"). A coded message may, therefore, be shorter than the original message.
It can also be made as long as or longer than the original message, if the codebook
Provides lengthy code phrases for single concepts or nonsense code groups for padding purposes. Such techniques can be used to make encoded messages harder for opponents to read.
